Organic light-emitting device and organic light-emitting display device

An organic light-emitting display device comprising:

• a thin film transistor on a substrate;
• a light-emitting element disposed on an active area of the substrate and connected to the thin film transistor;
• and
• an encapsulation stack disposed on the light-emitting element and including a plurality of inorganic encapsulation layers and at least one organic encapsulation layer disposed between the inorganic encapsulation layers,
• wherein the at least one organic encapsulation layer includes:
• a first organic encapsulation layer disposed on the inorganic encapsulation layer;
• and
• a second organic encapsulation layer surrounding the first organic encapsulation layer and including a moisture-absorbent material dispersed in the second organic encapsulation layer.

An organic light-emitting device having a substrate where an active area and non-active area are defined, comprising:

• an organic light-emitting element disposed at the active area;
• a first inorganic encapsulation layer disposed on the organic light-emitting element;
• a first organic encapsulation layer disposed on the first inorganic encapsulation layer;
• and
• a moisture absorbing layer preventing external moisture from penetrating into lateral sides of the organic light-emitting device and surrounding the first organic encapsulation layer,
• wherein the moisture absorbing layer is a second organic encapsulating layer including a moisture-adsorbent material dispersed in the second organic encapsulation layer.
